I've recently purchased and set up a maxpro3000 with a Se 2000 encoder. I'm still testing but early results are very impressive with great clarity and reasonable range even at low power.

I'm keen to patch a PC to the system so I can monitor all parameters via the studio PC instead of grovelling around in the rack.
I see the pins on the lcd display board for doing this but have no idea where to start. usb or Rs 232?
